Problems solved by technology

The horizontal single-axis or inclined single-axis tracking power generation system, which is the current mainstream in the market, has an increasing installed power due to the increase in component power, and its structural shortcomings are also becoming more and more obvious. It has gradually failed to adapt to the higher and more use requirements of future trackers.
Because the conventional flat uniaxial has only one rigidly supported driving point, the longer the length of the single column support, the easier it is to generate low-frequency resonance. At the same time, the torsional deformation of the main beam end of the torque tube at both ends of the driving point is easy to occur, which has suppressed the conventional flat uniaxial. Increase installed capacity and reduce cost per watt

Embodiment Construction

[0056]Such as figure 1 , shown in 11 and 13, in some embodiments, a single main girder drive solar tracking device includes a main girder 1 and at least one rotary speed reducer 10, the number of the rotary speed reducer 10 can be arranged according to specific conditions, It can be set to one or more than one, and the internal structure of multiple rotary reducers 10 is exactly the same; one of the rotary reducers 10 is connected to the motor 11, and the motor 11 is controlled by the motor controller, and the motor controller and the motor 11 They are connected by cables; the rotary reducer 10 connected to the motor 11 is the active rotary reducer 10, and the other rotary reducers 10 are driven rotary reducers 10, and the torque of the active rotary reducer 10 is transmitted to the slave through the transmission shaft 12. The rotary reducer 10 is driven, and the transmission shaft 12 rotates around the main beam 1 while propagating itself. Then the main beam 1 is driven to r...

Abstract

The invention discloses a solar tracking device driven by a single main beam. The device comprises a main beam and at least one rotary speed reducer, one rotary speed reducer is connected with a motor, the motor is controlled by a motor controller, and the motor controller is connected with the motor through a cable; a plurality of connecting pieces are distributed on the transmission shaft in the length direction at intervals, the connecting pieces are connected with the main beam through sliding rails, and the connecting pieces can slide on the sliding rails. The span between the two stand columns of the multi-point driving tracking connecting piece is large, and the problems of deformation caused by drooping of the transmission shaft, rotation oscillation caused by bending of the transmission shaft and discontinuous rotation caused by drooping deformation of the transmission shaft are solved.

Description

technical field [0001] The invention belongs to the technical field of solar power generation, and in particular relates to a solar tracking device driven by a single main beam. Background technique [0002] The proportion of solar photovoltaic power generation in the electricity market is rising rapidly, and the market prospect is extremely promising. In large-scale commercial power stations, the tracking power generation system is used to increase the power generation of the power station by more than 20% compared with the fixed power generation system. Therefore, there will be more and more commercial power stations using tracking power generation in the future, and the single main girder multi-point drive solar tracking power generation system is also ( Tracking Brackets) make more demands. The horizontal single-axis or inclined single-axis tracking power generation system, which is the current mainstream in the market, has an increasing installed power due to the incre...
